Its various generating sets are known. Since it is not a quotient of a dihedral group, it cannot be generated by two involutions. A generating set consisting of 4-5 involutions has been known for more than 15 years. In this talk I will show how it is generated by 3 involutions. <br class=""><br class="">--------<br class=""><br class="">To see the upcoming talks visit: <a href="https://researchseminars.org/seminar/BilTop" class="">https://researchseminars.org/seminar/BilTop</a><br class=""> <br class=""><br class="">Best,<br class="">Cihan Okay<br class=""><br class=""><a href="http://cihan.okay.bilkent.edu.tr/" class="">http://cihan.okay.bilkent.edu.tr/</a><br class=""></div>
